Special Issue Information

Dear Colleagues,

The depletion of natural resources and the impacts of waste emissions present challenges for modern society that must be addressed to ensure that future generations can live sustainably and with quality. Proposals that focus on resource recovery and reusing goods whose original functions have been exhausted represent strategic and urgent actions in pursuing a dynamic balance between the technosphere and the biosphere.

The first step in designing and implementing this approach is investigating the environmental impacts, economic factors, and social developments associated with such arrangements. To achieve this, various methods must be applied with care and rigor, including life cycle and economic and social assessments. These assessments make it possible to employ process simulation, Multi-Criteria Decision Analysis (MCDA), optimization methods, Circular Economy logic, and machine learning to balance the dimensions of the triple bottom line.

This Special Issue intends to be a forum for scholars to discuss conceptual constructs and report experiences where such approaches have been applied. By coordinating efforts and collaborations, we can make concrete contributions that enable managers to navigate their decision-making processes and develop plans, policies, and projects, addressing the unavoidable aspects of the current context. With this in mind, colleagues, researchers, and managers are invited to join this initiative.

In line with Saudi Arabia’s Vision 2030, this study reviews the green operations and environmental responsibility revolution in Saudi companies. The study also contributes new cross-sector empirical evidence from Saudi firms, a context that has received limited attention in previous green operations research. This study assesses sustainability advancements in 38 Saudi companies, employing a mixed-research approach. It examines the impact of (i) environmentally friendly technologies, (ii) employee training, (iii) assessing and reporting, (iv) transparent reports, and (v) adherence to recognized standards on sustainability practices through a detailed statistical and correlation analysis. To ensure thoroughness, the selected companies operate across various sectors, differ in sizes, and possess varying levels of experience. The analysis reveals how internal capabilities and governance mechanisms jointly support the operational adoption of sustainability practices in Saudi firms during the Vision 2030 transition. The findings presented have valuable insights for managers and policymakers seeking to promote sustainable practices within their organisations. Full article

Polyethylene terephthalate (PET) is one of the most widely used plastics globally, and its poor post-consumer management poses serious risks to the environment and human health. Tackling this issue requires innovative strategies that combine recycling and sustainable manufacturing with the principles of the circular economy. This study addresses this challenge by investigating the use of recycled PET, along with reverse logistics, to produce a cell phone holder through additive manufacturing (AM). Characterization was performed using differential scanning calorimetry, thermogravimetric analysis, intrinsic viscosity measurements, and mechanical tensile tests. Environmental and circular performance were evaluated using Life Cycle Assessment (LCA) and the Material Circularity Indicator (MCI), comparing production with 100% virgin PET resin and 100% recycled PET resin. The results showed that the recycled route achieved a tensile strength of 37.7 MPa, with 7.6% strain before rupture, and thermal analysis confirmed its stability during processing. The LCA revealed a 12% reduction in overall environmental impacts when recycled PET replaced virgin resin, with electricity consumption identified as the main critical point. The circularity assessment suggested potential savings of up to 70% if recycled PET products are reprocessed at the end of their life cycles. These findings demonstrate that combining open-loop recycling with additive manufacturing (AM) can effectively turn waste into high-quality, value-added products, advancing circularity and sustainable material innovation.

In light of the global raw material crisis and the ongoing degradation of the natural environment, this study provides a significant contribution to the advancement of the circular economy in the construction sector. The authors conducted a comprehensive analysis of the feasibility of using waste sands originating from wastewater treatment plants as substitutes for natural fine aggregates in concrete mixtures. The investigation included the evaluation of the physicochemical, environmental, and mechanical properties of the analyzed waste sands. The results demonstrate a high application potential for sewer cleaning sand (SC), which, in its current form, can be used in non-structural applications. The key advantages of the sand that was examined include a high sand-equivalent value (98.2%), low contents of impurities (LOI < 1.5%), and a favorable chemical composition. Leaching tests for harmful substances, including heavy metals, for both the sand and the mortar samples, did not indicate any significant environmental risk. One principal conclusion of the study is the identification of the possibility of closing the waste life cycle at the wastewater treatment plant stage, which could significantly contribute to the reduction of landfilled waste volumes and operational costs.

Current issues in sustainable development concern research on comprehensiveness, coherence and practicality. Therefore, the objective was to develop and test a novelty approach to product sustainability assessment based on life cycle, quality, and costs. This approach extends the iterative design thinking process (DT), including overcoming the limitations of existing LCSA methods. We present a systematic process for obtaining and processing customer requirements with a survey and Pareto–Lorenz analysis. Then, using an algorithm developed in Matlab R2021a program, we generated product prototypes considering the key criteria presented in various dimensions of current and modified states. Next, we propose the modeling of prospective LCA for all prototypes in the OpenLCA program with Ecoinvent database. Finally, we aggregated the results considering the cost of prototypes in environmental–cost analysis to determine the direction of product sustainability. We tested this approach in detail with the example of vacuum cleaners for domestic and commercial use. After a literature review and survey research in customers, we developed 54 prototypes, where the modified key quality criteria were as follows: vacuum in the suction pipe, engine power, operating range, and length of the power cable. Using this approach, it was possible to select six prototypes that best meet customer requirements, are environmentally friendly, and cost-effective. Finally, we discuss contributions to DT and LCSA methodologies, and propose future directions for development within the application of artificial intelligence (AI). This approach can be a practical application in SMEs already in the early stages of product development (conceptualization), where access to detailed data is limited. Full article
